| Which plan to pick | Free is fine for a document or two a day. Before paying for Plus, try NotebookLM, which is free, or use Claude or ChatGPT if you already pay for one. | Use the free credits to make two or three decks and judge the output. If you'll keep using it, Plus is the sensible step because it removes the badge and refreshes credits monthly. Only move to Pro if you want the API, custom domains or viewer analytics. | Standard covers most individuals; watch the usage dashboard on your first big job. Move to Business when several people need it or you want to run it on your own AI account. |
